思路：在点击保存按钮时，将标题和内容保存到集合中，自然想到应该是Dictionary<K,V>，而且用这个集合可以避免产生2个相同标题的日记。对添加到集合中的数据，采用二进制序列化到文件中，在程序执行目录中专门建一个“Notes”的文件夹存放日记文件，日记文件的文件名以标题命名。程序加载的时候，如果“Notes”文件夹下有文件，就在右侧列表中加载文件，点击时反序列化后显示在左侧。下面是具体代码：

在Form1类下定义一个集合：

 Dictionary<string, string> dic = new Dictionary<string, string>();

“保存”按钮的点击操作代码如下：

             var sTitle = txtTitle.Text.Trim();
             var sContent = txtContent.Text.Trim();

             dic.Add(sTitle, sContent);

             string fullPath = Path.Combine("Notes", sTitle + ".txt");
             using (FileStream fsWrite=new FileStream(fullPath,FileMode.Create,FileAccess.Write))
             {
                 //进行二进制序列化
                 BinaryFormatter bf = new BinaryFormatter();
                 bf.Serialize(fsWrite, dic);
                 MessageBox.Show("添加日记成功");
             }

在Form1_Load中的事件处理代码如下：

             string sPath1 = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
             string sPath2 = "Notes";
             string fullPath1 = Path.Combine(sPath1, sPath2);
             string[] strFiles = Directory.GetFiles(fullPath1, "*.txt");

             if (strFiles.Length>)
             {
                 foreach (string item in strFiles)
                 {
                     var s = Path.GetFileName(item);
                     listBox1.Items.Add(s);
                 }
             }

在listBox1_SelectedValueChanged中的事件处理代码如下：

           if (listBox1.SelectedItem!=null)
             {
                 var FileName = listBox1.SelectedItem.ToString();
                 var fullPath2 = Path.Combine("Notes", FileName);
                 using (FileStream fsRead=new FileStream(fullPath2,FileMode.Open,FileAccess.Read))
                 {
                     BinaryFormatter bf1 = new BinaryFormatter();
                     //进行二进制反序列化
                     Dictionary<string, string> dic2 = bf1.Deserialize(fsRead) as Dictionary<string, string>;
                     foreach (KeyValuePair<string,string> item in dic2)
                     {
                         txtTitle.Text = item.Key;
                         txtContent.Text = item.Value;
                     }
                 }
             }
             else
             {
                 MessageBox.Show("请选择要查看的文件");
             }

总结：

程序还有些Bug，因为主要的重点是放在序列化的使用上，日后如果有时间再完善功能吧。

1.对于新添加的日记，需要在下一次程序启动中才会加载到右侧listBox中（想法是做到保存后就加载到listBox）；

2.对于日记的修改，修改内容后，点击保存，可适时看到修改的变化；而如果把标题和内容都修改了，程序则认为是一个全新的日记（Dictionary集合会因为key的不同，而重新添加）。
